Why Toncan Iron was developed 




Toncan Iron is a scientifically refined open rust than the original iron. Later, it was demonstrated

What Toncan Iron offers its users 



• In thousands of laboratory and weather tests, and in countless service 
tests conducted for three decades in practically every industry, Toncan Iron 
conclusively has proved its possession of eight outstanding advantages. 
These are, briefly: 



1. It resists, to a higher degree than any ing, drawing, etc. — has practically no effect 
other ferrous material in its price class, the upon the rust-resistance of Toncan Iron. 



attacks of natural forces which cause rust and 



corrosion. 



Cjk m Its high resistance to rust and corro- 
sion is not confined to the surface or skin of the 
metal. Toncan Iron is uniformly resistant 
throughout its entire cross-section. 



O. It welds easily by any of the usually 
accepted modern methods. The use of Toncan 
Iron Welding Rod insures an installation of 
equal rust-resistance throughout. 



3. 



It combines with the high rust-resist- 



ance of an alloy iron many desirable physical 
qualities not found in the highest grade open 
hearth steels. 



/ . A uniform and tightly adherent gal- 
vanized coating can be applied, thus adding 
the protection of a coating of zinc to the 
already high rust-resistance of the base metal 
itself. 



4. 



It is one of the most ductile of materials 



It is remarkably soft. It forms easily. 



5. Unl 



O. Through its longer service life, it has 
been found to cost far less per year of service 
Its use is more than an economy. It is insur- 
ike other ferrous materials, cold ance against early sheet failures and fre- 



working— cutting, bending, punching, stamp- quent, costly replacements.

How Rust is Formed 




Rust, in technical terms, is iron oxide, a 
combination of iron and oxygen. Iron and 
oxygen will not combine directly except by the 
application of heat of at least 400 degrees 
Fahrenheit, in which case scale, or iron oxide,

2. (Oxidation) Oxygen unites readily with the 
dissolved iron to form rust.

such temperatures are not normally found in iron or steel do so through electrochemical 
practice, it is evident that nature forms iron solution of the iron and then, in the presence

Toncan Iron can be annealed at a temperature of

Physical properties and physical constants 



Toncan Iron is unique in that it combines with its tibility of the metal to heat treatment. It increases the

How to specify Toncan Iron Sheets 



Toncan Iron Sheets are stocked by jobbers in all large cities. 
Be sure to specify: VV A11 sheet metal work shall be rust-resisting Ton- 
can Copper Molybdenum Iron manufactured by Republic Steel 
Corporation.' 7 In cases where public institutions do not use trade- 
names in specifications, Toncan Iron Sheets may be specified as: 
11 Alloyed iron sheets of open hearth iron, copper and molybdenum 
produced by the basic open hearth process, containing no 



less than ,40 per cent copper and .05 per cent molybdenum." 
For your protection, every Toncan Iron galvanized sheet is 
stenciled at approximately two-foot intervals with the Toncan Iron 
trade-mark in green. Smaller formed products are die stamped with 
the trade-mark and maker's name. The gauge also is clearly shown. 
Look for the green Toncan Iron trade-mark — it's your assurance 
of longer sheet life, easier working quality, and greater economy.

Toncan Iron was used for all interior sheet metal work in the Seattle Art Museum. Architects, 
Bebb & Gould; consulting engineer, Louis Bouillon; general contractor, Peter J. G]arde; 
fabricator, Washington Sheet Metal Works. All are Seattle firms. 




Toncan Iron was used for the precipitators of the smoke-elimination device at the central 
heating plant, Washington, D.C., which supplies heat for all government buildings. Fabri-

After devoting months, even years, to the 
creation and design of a beautiful building 
or other structure, the conscientious architect 
seeks means of endowing it with permanence, 
by specifying those materials which will best 
meet his client's service requirements. 

Toncan Iron brings to the building in- 
dustry the highest degree of resistance to rust 
and corrosive action obtainable in ferrous 
sheet metal to be found in its price class. It 
also insures economy of installation, through 
its unsurpassed ductility and working quali- 
ties. The truth of every claim made for Toncan 
Iron as to its durability, economy, and other 
superior merits is attested by many of 
America's leading architects.

Toncan Iro/, because of its versatility, has 
been given wide usage by engineers and has 
proved its value on countless installations 
under severe service conditions. 

Engineers use Toncan Iron for roofing, 
siding, and all other exterior applications 
called for in the specifications. Heating and 
ventilating engineers specify Toncan Iron for 
all sheet metal work in heating and ventilat- 
ing installations. It is an ideal material for 
water line mains, etc. Maintenance engineers, 
mechanical engineers— in short, all types of 
engineers who are concerned with the un- 
ending battle of industry against the forces of 
rust specify Toncan Iron for sheet metal work 

Scattered throughout the following pages 
are a few of the many uses for which engineers 
specify Toncan Copper Molybdenum Iron, 
the sheet metal that continues to build new 
records of rust-resistance, endurance, and 
economy with each passing year of service.

Toncan Iron Sheets for ducts and other 
sheet metal applications in air condition- 
ing are establishing exceptional records 
for long life under severe conditions. 

In the selection of ferrous materials for 
air-conditioning systems, there exists the 
ever-present problem of combating corro- 
sion in (1) central station air-conditioning 
units and (2) ducts through which the con- 
ditioned air is carried to different parts of 
the building. Replacement of failed metal 
parts in air-conditioning installations is 
an extremely costly matter. Hence, insur- 
ance of maximum life for these parts is a 
fixed responsibility of the architect or engi- 
neer. The life of galvanized ferrous sheets 
in duct systems is affected by: 

1. Moisture originally present in the air as 
water vapor, or as moisture held in mechanical sus- 
pension, deposits out on the sheet as a result of 
temperature changes. 

2. Moisture deposits out in certain critical 
areas of the ducts, as a result of the circuitous, 
angular paths often necessary. 

3. Moisture deposits out, as a result of the 
presence of dust particles or hygroscopic products 
of corrosion. 

4. Improperly or insufficiently washed or fil- 
tered air contaminates the moisture with sulphurous 
acid, sulphuric acid, and hydrogen sulphide. 

Toncan Iron has demonstrated its 
ability to prolong the life of air-condition- 
ing equipment through its resistance to 
these corrosive conditions.

Railroads 



Many significant applications of 
Toncan Iron are to be found on and 
around railroads, where safeguards 
against the contaminated sulphurous 
products of combustion and conden- 
sation are necessary. 

Roundhouse maintenance engi- 
neers successfully use Toncan Iron 
sheets for exhaust ducts. Toncan Iron 
plates have proven ideal for cross- 
ings and bridge decks, where corro- 
sion from smoke, soot, brine drip- 
pings, etc. is liable to cause trouble. 
Locomotive fire-boxes represent an- 
other important application of Ton- 
can Iron plates. 

Continued, dependable service 
has established for Toncan Iron a 
recognition among its users as being 
one of the most satisfactory materials 
obtainable for railroad service. 



"We are well pleased with tKe performance of 
Toncan Iron," -writes the engineer inspecting the 
property of The Chicago Rapid Transit Co. This 
company, realizing that rust attacks coaches 
which must operate in all kinds of weather, 24 
years ago specified Toncan Iron Sheets for the 
roofs of 250 cars. Toncan Iron has, for years, been 
used by The Chicago Rapid Transit Co. for 
maintenance work. 



In the roundhouse of Norfolk 8c Western Ry. Co., 
Williamson, W. Va., the ducts which carry smoke 
from locomotives to the main pipe were lined with 
Toncan Iron. Furthermore, Toncan Iron Plates 
were used for five exhaust stacks.

Salt water corrosion is based, pri- 
marily, upon the capacity oi salt water 
to act as a conductor of the electrogalvanic 
currents set up when dissimilar metals, or 
metals containing oxide or slag inclusions, 
are subjected to it. Toncan Iron is able to 
combat this type of corrosion successfully 
because, unlike steel or the slag-contain- 
ing irons, it is practically free from 
inclusions. It does not, therefore, permit 
the formation of thousands of destructive, 
galvanic cells. 

For installations calling for the sub- 
mersion of metal in salt water or for sea 
board structures subjected to salt air 
atmosphere, Toncan Copper Molybdenum 
Iron consistently performs better than any 
ferrous material in its price class.

Regardless of whether you buy ordinary 
tal roofing products or Tone an Iron Roof- 
ing Products, several of the larger items 
that make up the final cost remain the same. 
As examples, consider the cost to the manu- 
facturer of forming the sheets, the cost of 
shipping them to you, and the labor cost of 
applying them to the building. The only 
added cost for products made from famous 
Toncan Iron is a small one. 

So why not use Toncan Iron Formed 
Roofing Products? They can be depended 
upon to outlast those from ordinary metal by 
many years. They resist rust and corrosion 

longer.

Y-CRIMPED ROOFING 

• V crimped is the oldest form, of roofing, and 
has been used extensively. The construction is 
simple and makes a good appearance at 
reasonable cost. This roof can be applied over 
close sheathing, to strips spaced four or five 
inches apart or over old shingles. The 3V- 
crimped is a pleasing variation from the stand- 
ard and makes a stiffer sheet, while 5V- crimped 
is still stronger. All three styles are supplied in 
lengths of 5, 6, 7, 8, 9, 10, 11, and 12 feet and 
in gauges 24 and lighter. Actual covering width 
of each style is 24 inches.

CORRUGATED 






CORRUGATED SHEETS 

• Corrugated sheets offer the advantage of light 
weight with great lineal rigidity. This advantage, plus 
the fire protection offered by corrugated sheets, 
accounts for their almost universal use in roofing and 
siding for industrial buildings, warehouses, mine 
buildings, and other large structures in the vicinity 
of railroads. Corrugated sheets are also an ideal 
material for barns, garages, sheds, and a wide 
variety of other buildings. The 1 34-inch style is sup- 
plied in gauges 20 and lighter; the 2 ' _.-inch style in 
gauges 10 and lighter. Both styles are 26 or 27 ] L > 
inches wide; lengths, 5, 6, 7, 8, 9, 10, 11, and 12 feet. 




ROLL ROOFING 

• Especially useful 
where pitch of roof is 
slight and for wide 
areas. Cross seams are 
double locked. Each 
roll contains 50 lineal 
feet. Covering width is 
24 inches. Gauges 26, 
28, and 29. 



CROSS-CORRUGATED SHEETS 



PRESSED STANDING SEAM ROOFING 




• Used for elevators and other high buildings where there is some 
motion of the building in the wind or where the structure may settle. 
The nails in each sheet are driven 2 inches above the edge of the sheet 
below, which allows the building to settle or move without loosening 
the sheets. The standard size for this type of sheet is 26 x 32 inches, 
providing for a covering width of 24 inches, with a 2 inch lap.
